SUBSOIL-PLOW.

Specification of Letters Patent.

Patented Nov. 25, 1913.

Application filed November 4, 1912. Serial No. 729,194.

To all whom it may concern:

Be it known that I, CHARLES W. HICKS, a citizen of the United States, residing at Clearwater, in the county of Pineallas and State of Florida, have invented new and use ful Improvements in Subsoil-Plows, of which the following is a specification.

. This invention-relates to attachments for subsoil plows, and it comprehends, briefly, certain hereinafter described improvements in the type of attachments shown in my prior application, Serial Number 707,576, filed July 3, 1912. The improvements in question reside primarily in the construction of the guide brackets associated with the shoe-carrying bar, the mounting of said brackets upon their supporting bar, and the devices employed to connect the same with the plow beam, their object being to avoid and correct any deviation of the shoe from its proper working position, and, also, to permit the employment of the ordinary furrow-turning share or' with a middle breaker.

An embodiment of the invention is illus trfated in the accompanying drawing, whereo z c Figure 1 is a side elevation of a plow equipped with the improved attachment; Fig. 2 is an enlarged plan view; of the at-' tachment, the plow beam being shown in sec tion, and the shoe-carrying bar omitted; Fig, 3 is a perspective view of the attachment, with the upper guide bracket removed from its supporting bar, the shoe and a portion of its bar being shown.

The plow represented in said drawing is of the conventional goose-neck style, and comprises, generally, the curved metal beam 1, handles 2, and share '8. These parts are of the ordinary construction, and the term share, as applied to the last-mentioned element, is employed in its broadest sense, i. e., as indicating any one of the commonlyused ground treating devices, without reference to the specific structural characteristics thereof; it is here shown as a furrow turner.

The sub-soil attachment is located between the handles, and to the rear of the beam, as shown, its chief element being the vertical bar 4: which is formed along one edgewith a series of notches 5 and carries at its lower end the shoe'6. To guide this bar in its movements, upper and lower brackets 7 and 8 having slots 9: andlO are employed, said brackets being connected to and carried by a suitable supporting bar 11 which, in turn, is connected to the beam.

In the present embodiment of the invention, the aforesaid supporting bar 11 has the shape of a right angle, its horizontal upper arm being provided with a terminal clamp 12 that is similar, in the main, to the corresponding element shown in my previouslyidentified' application, to which reference maybe had fora complete description; it is sufficient to state, therefore, that the jaws of the clamp straddle the grooved plow beam and grip the same at opposite sides, suitable clamping bolts 13 being employed to hold theljaws in place. The arms of the supporting bar are connected. by a diagonally-arranged brace rod 14- which is detachably fastened atits ends to lugs 15 formedon the arm ends, as depicted in Fig. 8, the rod having, by preference, anarcuate shape to permit it to pass under or over any of the usual connecting braces carried by the plow proper,= which braces, might otherwise interfere with its, attachment to the supporting bar:

Asmore particularly regards the guide brackets above referred-to, it may be stated that the lower bracket 8, fo-r reasons hereinafter explained, is of duplex formation; that is to say,- it comprises a p'air'of counterpart members which are located upon opp0- site sides of the vertical arm of the supportingbar 11 at the. lower end thereof and occupy acommon horizontal plane. The upper bracket: 7 his removably mounted upon. the

rear end of the horizontal arrri of bar 11, and is of substantially angle section, its horizontal, upper plate-like member or wing, wherein the slot 9- is formed, being extended a slight distance beyond the vertical wing to produce a supporting lip or flange 16 that is adapted: to rest upon the upper edge of the horizontal arm of said bar 11. The vertical arm of this bracket may be placed against either side face of the horizontal arm of bar 11, according as it is to cooperate with one or the other of the members of bracket 8, and it is formed adjacent each end with an opening 17 through either. of which a fastening bolt 18 may be passed to attach the bracket to its supporting arm, the stem of the bolt passing through a short longitudinal slot 19 in said arm. This construction, as.v will be understood, alfords a 1 are arranged in the manner shown, with the bar at disposed upon the right-hand side of bar 11, but in the latter instance, (which it is deemed unnecessary to illustrate), bar 4 is arranged upon the left-hand side of bar llso as to dispose the axis of the shoe'in line with the center ofthe middle breaker. By adjusting the slidable upper bracket, the shoe 6 may be caused to enter the ground in the proper position, thus rendering it possibleto initially position the shoe correctly,

or to reposition the shoe if, for any reason,

it has assumed an incorrect position during either the connectionbf the attachment to ,theplow, or when the latter is in use; 5; In addition to the clamp 12, the attach ment is preferably fastened to .the plow through the agency of a rod 20. This rod, which is of considerable length, is provided at its front end with an eye 21 that may be engaged with'any one of the usual plow bolts; for example,- one of the bolts 22 used to fasten the share to the beam. The. rear half of saidrod is threaded, and this portion is passed through any one of a vertical series of perforations 23 formed in a vertical flange 24 that projectslaterally from the front edge of the depending arm of bar 11,

' the flanger being-- preferably integral with said] arm and p the adjacent member of bracket 8. As a result of this construction, the

connecting rod- 20 may be fastened insdi fi'erent positions and at different-angles, to insure the retention of the supporting bar in proper-position relative to the plow proper, suitable fastening nuts 25 being employed to secure therodas adjusted, these nuts engaging against the opposite faces of jflange 24. 7

'To retain the shoe carrying bar 4: in adjusted-position, a suitable key 28 or the like may be employed; V 'Ielaim:" V
